In addition, as shown in Fig. 3 (b), as cognizance code 150a, can replace bar code and use QR code.Therefore, in this case, the code reader 112 shown in Fig. 4 changes to the mechanism that reads cognizance code 150a.

And then in the case of using such special tube core 150, the inner housing 111 shown in Fig. 4 changes to the parts in large footpath for this special tube core 150 is installed.

In this case, by jut 120b and the recess (not shown) of the inner housing 111 in large footpath are fastened, thereby can make special tube core 150 fixing with respect to inner housing 111.

In the following description, the situation of preparation syringe 104 monomers shown in direct installation diagram 3 (a) is described.

As shown in Figures 1 and 2, in Fig. 4, drive end bearing bracket 102 is mounted and fixed in the framework 101 of medicinal-solution administration device 100.

Inner housing 111 can in framework 101 and drive end bearing bracket 102 is interior carries out sliding action along fore-and-aft direction (left and right directions in Fig. 4 shown in arrow), at inner rear storage piston unit 116, and can forwards extrude the medicament in preparation syringe 104.

Preparation syringe 104 is by with respect to inner housing 111 restriction sites (being fixed as mounting or dismounting freely when installation).Thus, be arranged on the position that cognizance code 104a can be read by code reader 112.

It should be noted that, cognizance code 104a is configured to and can on the length direction of preparation syringe 104, be read.

Position detecting mechanism 114 is configured to and comprises with predetermined distance and be configured in the reflection-type at three places or the optical sensor 114a～114c of infiltration type.

Wherein, whether optical sensor 114a detection inner housing 111 is positioned at pricker position.In addition, whether optical sensor 114b detection inner housing 111 is positioned at and pulls out pin position.And then whether optical sensor 114c detection inner housing 111 is positioned at the position of reading of cognizance code 104a.

Shutter 114d is by when along fore-and-aft direction sliding action, the light of optical sensor 114a～114c being blocked or let pass, thus the position of detection inner housing 111.In addition, shutter 114d is integrally formed with the housing 115a that is accommodated with piston actuated motor 115.Housing 115a is connected with inner housing 111 and sliding motor 113, can carry out sliding action along fore-and-aft direction by the rotation of sliding motor 113.

The read method of cognizance code 104a based on above structure is below described.

Next,, in step S152, position detecting mechanism 114 determines whether that being positioned at code reads position.

At this, in the time being judged to be to be positioned at code and reading position, in step S153, read the cognizance code 104a of preparation syringe 104 by code reader 112.In fact, as mentioned above, by the driving of sliding motor 113, the position that shutter 114d rearward slides and is blocked between optical sensor 114c temporarily stops.Then,, by the reversion of sliding motor 113, the position that shutter 114d forwards slides and is blocked between optical sensor 114b stops.When along this fore-and-aft direction (preparation syringe 104 axially) reciprocating action, code reader 112 reads the cognizance code 104a of preparation syringe 104 via peristome 111a.In the present embodiment, in step S154, again read cognizance code 104a by code reader 112.Thus, once reading in action, in the time carrying out front and back reciprocating action, there is the chance of twi-read cognizance code 104a, by obtaining twice cognizance code 104a and comparing, read precision thereby can improve.Certainly, reading also of cognizance code 104a can only be carried out once.

In step S155, microprocessor 121 compares the information reading from the cognizance code 104a of preparation syringe 104 and the determinating reference being kept at memorizer 126, if preparation syringe 104 is suitable, enters medicament delivery step and carry out medicament delivery processing.

That is, by driving sliding motor 113, make forwards side shifting of inner housing 111, and entry needle 110 is moved in the front of end cap 102 forward from front end opening 102a, thus human body is punctured.

It should be noted that, for example implement together with degasification action by read action and the warming up before medicament delivery that make cognizance code, thereby can shorten the preflood time.Now, become in the preparation syringe of judging object and be not limited to only enclose a kind of preparation, also have the situation that has several formulations of enclosing.Now, in addition the kind of the preparation in preparation syringe is differentiated.

Next, drive and piston unit 116 is forwards moved with motor 115 by driven plunger.Thus, via entry needle 110, the preparation of the amount that is kept at the setting value in memorizer 126 is thrown in from preparation syringe 104 to human body.

It should be noted that, in above operation, when failing whether be positioned at code read the judgement of position in step S152, to step, S156 divides a word with a hyphen at the end of a line.And, in step S156, not can read the time if be judged to be and become timing done state, divide a word with a hyphen at the end of a line to step S157.On the other hand, the in the situation that of non-timing done state, return to step S152.

In step S157, by driving sliding motor 113, the rearward home position of inner housing 111 is moved.Then, the mistake demonstration on display part 109 etc. is carried out to fault processing.

In addition, when being judged to be preparation syringe 104 improperly in situation in step S155, in step S158, carry out mistake at display part 109 and show.Then,, in step S159, drive the sliding motor 113 and rearward home position of inner housing 111 is moved.And, in step S160, preparation syringe 104 is taken out from inner housing 111, and return to step S150, from being installed, the operation of other preparation syringes 104 starts to rework.
